Title: Method of and apparatus for dewatering plastic materials
IPC: B29C48/03
Filed: 1960-11-28
Abstract: 927,330. Presses for separating liquids from solids. WELDING ENGINEERING Inc. Nov. 28, 1960 [Dec. 1, 1959], No. 40788/60. Class 46. [Also in Group V] A method of separating drainable liquid from a solid material containing such liquid consists in compacting and squeezing an outer portion only of said material while moving it generally helically forward around a predetermined axis, continuously causing the separated liquid to flow rearwardly for removal, subjecting the resulting material and remaining liquid to high pressure mastication while retaining and heating the remaining liquid, and then conveying said material to a space of lower pressure to induce vaporization of the heated liquid. Plastic material, e.g. synthetic rubber containing water, is extruded with removal of the water by feeding the material via a hopper 16, Fig. 2, into a de-watering extruder section comprising an inclined longitudinally grooved barrel containing a helical worm 34 spaced from and carried by a rotary shaft 33. Water is squeezed from the material by the worm and flows rearwardly between the worm 34 and the shaft 33, and through a U-shaped arrangement of conduits 70, 73, Fig. 7, from which it flows to a drain 76 over an adjustable weir 74. Jackets 45 to 48 for temperature-controlling media, e.g. water and steam, are provided. At the outlet portion of the de-watering section the shaft 33 has a helical worm 42 integral therewith for feeding the material via a conduit 31 to the inlet 54, Fig. 6, of a drying section of the extruder. The latter contains two parallel worms 26 having reverse pitch portions 61, kneading portions 62 for removal of water vapour through an outlet 63, and an end section 64 leading to a die 66. Heating jackets assist the removal of water vapour. The flow through the drying section is controlled by a plug 57 movable by an electric motor in response to the temperature of a thermocouple 60 at the die 66. Specification 733,911 is referred to.

Title: Covered die closing unit for injection moulding machine
IPC: B29C45/68
Filed: 1972-09-05
Abstract: 1386978 Machinery safety devices K HEHL 5 Sept 1972 [15 Sept 1971 19 April 1972] 41146/72, Heading F2J A guard for enclosing the moving parts of an injection moulding machine comprises two axially movable telescoped covers 23, 17, the first cover 23 of which is slidable relative, i.e. over, cover 17 between an open position and a closed or safe position in which it covers the fixed and movable dies 2, 5 of the machine, and the other cover 17 of which is similarly slidable relative, i.e. under, cover 23 between an open position and a closed position in which it covers the hydraulically actuated die-operating driving toggle linkage 7, 8, 9. The covers 23, 17, when in their normal jointly closed positions (Fig. 1), centrally overlap such that a pair of microswitches 21, 22 on cover 17 engage cam surfaces 25 of a rod 24 on cover 23 (Figs. 1 and 2) whereby the electrical main circuit of the die-closing unit is interrupted whenever one of the two covers is moved out of its closed position (Figs. 3 and 4). Additionally, the cover 23 has an axially projecting link 29 formed with an inclined cam slot 31 which co-operates with a central pin 32 of a shut-off valve unit 30-33 to block the hydraulic circuit of the die-closing unit whenever the die cover 23 is removed from its closed position. The covers 23, 17 are of inverted "U" section, to cover both the top and sides of the relevant working spaces, and are respectively carried by roller pairs 26, 27 and eye brackets 18, 19 on parallel guide rods 13, 14. When the power mechanism linkage is exposed by opening cover 17 and the electrical main circuit is interrupted, a machine setter may still operate the machine for testing and adjustment purposes following a change of dies &c., by a shunt switch in the main circuit which by-passes the electrical safety interlock, the hydraulic circuit remaining functional whilst the cover 23 is closed. A similar arrangement is illustrated in Figs. 9 to 12 (not shown), in which opening and closing of the telescoped covers 23, 17 is effected by a pneumatic piston/cylinder drive mechanism (34-38) arranged therebetween and manually operated by a three-way valve (42). The covers 17 and 23 may be locked in their closed positions, wing nuts 15 securing cover 17 and a lock pin (not shown) through link 29, of cover 23, engaging a bore (49) on die mount 2 (Fig. 11, not shown).

Title: Traveling wave tube with efficiency-enhancing focus field jump
IPC: C05G3/90
Filed: 1965-09-29
Abstract: 1,103,460. Travelling wave tubes. WESTING- HOUSE ELECTRIC CORPORATION. 29 Sept., 1965 [14 Oct., 1964], No. 41350/65. Heading HID. The focusing field of a travelling wave tube has a discontinuity over a region of the beam path between the gun and the collector so that the slower electrons of the beam are radially deflected and collected by the slow-wave structure. This permits an increase in power output under relatively high RF drive operation and increases the basic efficiency of the tube. The beam may be focused by a solenoid and the discontinuity produced by surrounding a portion of the tube with a sleeve of soft iron; the sleeve may be positioned a distance from the gun which is three-quarters of the beam length and occupy a tenth of this length or one or two wavelengths of the RF energy on the beam. Alternatively, the beam may be electrostatically focused by using a bifilar helix split into two longitudinally spaced portions to provide the discontinuity, the two delay line portions being coupled by a simple helix.

The external leads are retained in a temporary removable header 4 of e.g. high temperature polypropylene polyethylene, fluorocarbon, or fibre loaded polypropylene, and the header is placed in one of a series of lipped apertures 32 of a metal holder with the semi-conductor body dependent over an appropriate sector shaped cavity 41 of a mould assembly 40 having critical depth. The mould assembly may be of talc filled polypropylene homopolymer, normal polypropylene, polyethylene, silicone rubber, fluorocarbon, or metal with a release agent, and a predetermined quantity of a suitable plastic material (epoxy resin or diglycidyl ether of bisphenol, with anhydride curant) is dispensed to the mould. The protruding dependent semi-conductor assembly is then immersed in the plastic charge without overflow or contact with the header, partially heat cured, withdrawn, and the header removed; after which the encapsulated device is completely heat cured.

Title: Combined coin sorting and distributing devices
IPC: G07D3/12
Filed: 1977-10-06
Abstract: In the coin-sorting unit, the inserted coins (11) of various types run on a sorting rail (10) through sorting sections, in each of which coins (11) of the same type are transferred by a deflector (15, 16, 17) into a coin shaft (12, 13, 14). Each sorting section has a plurality of deflectors (15, 16, 17) and coin shafts (12, 13, 14), assigned to these, for coins of the same type, as well as a deflector control which, depending on the filling state of one or more coin shafts in each sorting section, controls the deflectors automatically from an effective position into an ineffective position, and vice versa. In the coin-dispensing unit, each coin shaft (12, 13, 14) is assigned a counter (21) for counting the coins (11) ejected from a coin shaft. This counter is designed as a differential counter and is assigned at least to each of the multiply provided coin shafts (12, 13, 14) for coins (11) of the same type, in order to balance the number of coins fed to the respective coin shaft (12, 13, 14) and extracted by ejection. The deflector control controls the deflectors (15, 16, 17) in dependence on the count of the differential counter. Because the counters are connected to a computer, the total amount of coins can be determined at any time. <IMAGE>
